' invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to lubricators for supplying oil and graphite to cylinders and is to be used on a steam cylinder.

shaft bearings; and it consists in the novel construction and combination of the parts hereinafter fully described and claimed. I, In the draWinga Figure 1 is a vertical section through the lubricator. Fig. 2 is a cross-section, taken on the line a:x in Fig. l. A is the casing of the lubricator valve. B and C are two cups or compartments for oil and for graphite, one or both of which may be used.

D is the valve of the lubricator which is conical in form, and which is journaled in the casing A. The valve is provided witha' spring (1 at its smaller end for holding it to its seat in the casing, and d is a screw engaging with the smaller end portion of the valve and atiording a means for adjusting the tension of the said spring; The compartments B and Q are provided'with outlet holes I) and 0, respectively, which communicate with the valve chamberv of-the casing.

E is the delivery pipe which prcjectsfrom the casing A, below the cups B and C, and which is connected to the engine cylinder or any portion of a machine which is to be lubricated.

The valve Dis provided with two cavities or slots'g and h in its periphery, which communicate with the holes I) and 0 respectively when turned upward, and which communicate with the delivery pipe E when turned downward.

Exhaust holes g and 7b" are provided in the side of the casing A when the lubricator A spring scra er G is secured in the delivery passage of t e casing A in the path of the cavity h which delivers graphite to" assist in discharging the graphite from themrvityl This spring scraper is pressed downwardly by the periphery of the'valve when the and which is journaled on the valve.

cavity or slot is turned upward. The valve is revolved step by step by any approved driving mechanism. Q

I is a ratchet toothed wheel secured to the valve, and i is a lever provided with a forked end portion 2" which straddles the whegll 1s adriving pawl pivoted to the said lever and engaging with the teeth of the ratchet wheel. A check pawl or spring 1' is secured to the casing A, and also engages'with the ratchet wheel so that it cannot revolve backward.

K is an operating rodwhich is connected to any convenient reciprocating portion ofthe engine or machine. y

L'is a disk which is adjustable longitudie nally on the lever i, and which is secured thereon by means of a set-screw k. The rod K is pivoted on the smooth portion 7c of the set-screw It so that it rocks the lever back and forth and revolves the valve. The valve can be revolved at any. desired speed by adjusting the position of the disk L on the lever.

M is a crank-handle secured to the valve for the purpose of revolving it hand whenever necessary, or before the engine restarted. The graphite and the oil descend intothe cavities by gravity when said cavities are placed in communication with the cups or compartments, and the said cavities are emptied of their contents when turned downward by gravity and by the spring'scraper. The exhaust holes relieve the cavities ofsteam' pressure when being moved upward and after the lubricant hasbeen discharged from them, so that the steam is not carried up into the on s. i

y the use of this device oil and graphite can be fed simultaneously, and the oil assists in carrying down the graphite in the delivery pipe.

In this manner the cylinder can besupplied satisfactorily with both oil, and graphite in definite roportions/which can 'not be accomplishe satisfactorily when a I 2.
